The Hundred Line -Last Defense Academy- is a survival-themed school-style tactical JRPG where sacrifice, friendship, and despair come together in the final 100 days.

A normal day – and its downfall
Takumi Sumino was once just an ordinary high school boy living in the Tokyo Residential Area. Every day was the same – peaceful, boring, and nothing bad happened. Until everything disappeared in the blink of an eye. Strange creatures suddenly descended on the city and destroyed it. A mysterious entity named Sirei appeared, offering Takumi a supernatural power – if he dared to stab himself to activate it.
Last Defense Academy – where life is limited to 100 days
Takumi wakes up in a giant academy in the middle of nowhere, surrounded by a supernatural wall of fire. Along with 14 other students, he becomes a member of the Special Defense Unit – the last line of defense against the monsters that are invading every day. Each student possesses Hemoanima – a form of mutant blood that grants them extraordinary powers. But is it a gift… or a curse?
Tense tactical combat
Combat is not just about showing strength – it is also about calculation, coordination and sacrifice. In each battle, you will control a group of students defending against fierce attacks. Take advantage of each character’s specialized skills to change the situation on the battlefield, and protect what is left of the Academy.
Beyond War: Friendship and Choice
When not fighting, players can spend time exploring, building relationships with team members, or crafting gifts to strengthen their bonds. It is the choices you make during this brief period of peace that will determine the outcome – will you choose to save humanity, or risk everything to keep what you hold dear?
Conclusion
The Hundred Line -Last Defense Academy- is a game where beliefs are tested, the price of power is exposed, and humanity becomes the only light in the apocalypse. The story will take you from skepticism to emotion, from anguish to hope… Only 100 days – what will you do to write the ending?
